Eventually yes, this could be an option. Although as mentioned the
primary target is TCG and while ideally the tests should run on both,
behaviour between the two is not always identical.

I have to note that this work initially was targeting not only guests
but also physical platforms for very basic testing, and later I
dropped some parts to shape it around the virt machine model.
